There are many global macro investing strategies that make use of the yield curve. While primarily used to trade bonds, there are also several good uses for trading stocks and currencies as well. In fact as powerful as the yield curve is, there is likely a few yield curve strategies for every asset class out there.

So what is the Treasury yield curve? It is the curve you get when you plot out the yields on different maturities of Treasury securities. For instance if you take the ninety day Treasury bill, the two year Treasury bill, five year Treasury note, ten year Treasury bond, and the thirty year Treasury bond you will get a curve. Usually sloping upwards from the bottom left to the upper right of the plot area, it can also take several other shapes. It can be very inverted with the far right down at the bottom and the far left at the top, it can have seemingly random lumps, and it can shift anywhere on the plot area. Each of these shapes and slopes of the yield curve tell the global macro investor something differently about the economy and the different trading instruments available to you.

Of course being able to tell what will happen in the economy does not always translate to being able to profit from it as the markets sometimes do their own thing, or at least that is how it can seem. So how does one apply the yield curve to their trading? The primary rule of thumb is that an upwards sloping yield curve is bullish for the economy while a downwards sloping yield curve is bearish. The steeper either curve is the better or worse it is. At least these are the general rules.

You may be asking yourself why this is. The reasons are actually fairly simple and straightforward. If the curve is steep, meaning the short term rates are low and the long term rates are high it means that banks are lending as they are able to borrow short term from the Fed and charge long term rates to their customers. Obviously when business is good for the banks, they will be lending as much as they can. This in turn spurs new business spending as money is available.

If the curve is inverted however business is usually about to slow down, rates will be lowered, and bonds will climb. This is because with the incentive of the banks to lend now gone they will throttle back and the spigots of available money run dry. In turn this forces the Fed to lower short term rates, the Fed Fund rate, in order to spur business growth once again. When they lower rates bonds inevitably go up.

Bonds and rates are like a piece of wood straddled on a log. If you sit at one end the other end goes up. If bonds are at one end yields are at the other. When yields go down bonds go up and vice versa. This is almost always the case, especially in an inflation environment.

If this is the case then anytime you can forecast the yield curve to show when the Fed will be lowering rates you can jump on it and go long bonds, typically with little risk. At the same time whenever you see rates being lowered you can wait a while and then go long stocks.

Of course as with all things in the market nothing works every time. In fact the quote history never repeats itself, but it often rhymes is a very appropriate statement. Used along with proper risk controls the yield curve can become one of the global macro investors best timing tools and economic gauges.
